Coryphantha sp. &nbsp &nbsp 7/31/19 Another Coryphantha that I would very much like to have identified. Any ideas? It is so different from the several other species that I have (they all look alike) that I think any true cactus nut could give me an id. It's a big plant - bigger than two male fists. You can just see the edge of its 5" (12.5 cm) pot. (88/88)
